Thank you for viewing. This is a listing for the Game Boy Advance KONAMI Duel Monsters Expert 3 game cartridge only. This is part of a collection clear-out. The battery has been replaced with a new one, the terminals have been cleaned, and the game has been tested and confirmed to be working. Please note that price reductions are not possible. The game software... I think it's in good condition, aside from some scratches on the insertion part. Please check the attached images. Due to its age, if you are sensitive to such things, please refrain from purchasing. In addition, there are no pets involved. After purchase, I will package it with waterproof measures (in a plastic bag) and cushioning material, and ship it anonymously via Yu-Packet Post Mini within 24 hours. #Nintendo #Nintendo #Retro #Valuable #RetroGame #KONAMI #GameBoyAdvance #Other #YuGiOh #gameboy
